Survey sites are not that bad, some of the offers claim to generate over $$$ a month. Like this 2017 Survey that make money video. I work for 5 companies: GlobalTestMarket, Ciao, OpinionWorld, LightSpeed, IPSOS They pay for completed surveys between £1.00 to £5.00
Look for companies that provide 2 Tier affiliate commission programs. This is a great source of passive income for you.
